Application filed. June 9, 1915. Serial No. 33,074.

To all whom it may concern:

citizen of the United Elizabeth, in the county and Time-Locks; and I dodeclare to be the invention, such as will skilled in the art to which itmake and use the same,

to th letters and figures there it known that I, EDWIN S. PHELPS, aStates, residing at of Union and State ew Jersey, have invented certainnew useful Improvements in Recording the following description of enableothers appertains to reference being had drawings, and to the ofreference marked a part of this specifia full, clear, and exact eaccompanying on, which form cation.

My invention relates to t1me-record1ng locks 111g in which is made arecord of throwthe lock-bolt in opening and also in closing the door aswell as the length of time also the door has remained unlocked andlocked, the dial upon which the record is made being divided into hoursand fractions of hours of the day so that it will furnish a permanentand reliable record indic the ating to the proprietor or manager time ofclosing the store at the end of business and the time of opening forbusiness as well as furnishing a record whether the store has beenopened between such times and the length of time it remained open.

One object of the present invention is to enable the recording mechanismto be located at a point remote from the door carrying the lock to beand whose movements are recorded so that the same opportunity is notafforded for tampering with the record as when it is carried the lock,

mech

ing and shutting the door.

on the door withand so as to relieve the recording anism fromdisturbances due to open- It also makes it possible to have therecording mocha-- nisms of a number of doors to be actuated or drivenfrom a central motive power so that drive ject to provide for all therecording mechanisms will be 11 in unison. It has also for its obshifting the marking stylus from one position to another to record doorthe locking and the unlocking of the by an electric circuit controlledby a switch operated by connections with the door provide for the the dor th bolt. It has further for its object to compulsory throwing ofoor-bolt to the completion of its stroke before it can be retracted rownin the other direction thus posicasing, showing the lock-bolt andcircuit controlling switch in the unlocked position of the bolt;

Fig. 12 is a diagrammatic view having a number of vrecording mechanismsfor as many locks connected with the central clock mechanism from whichpower is transmitted to the several recording mechanisms.

In the drawings the numeral 1 designates a casing containing anypreferred type of clock mechanism 2, a recording mechanism 3,e'lectro-magnets 4:, the armatures of which are connected as hereinafterdescribed with the recording mechanism, and battery-cells 5 from whichthe electro-magnets derive their energy. This casing will be supportedupon the wall or other suitable support in the room of the buildingwhere located.

Upon the door, the operation of whose lock in the act of locking andunlocking is to be recorded, is placed the lock-casing 6 which containsthe lock-bolt 7 and its manipulating parts and also electric-circuitcontrolling switch mechanism 8 which will be electrically connected withthe electromagnets of the recording mechanism so that the movement ofthe lock-bolt in locking and unlocking the door will be reliablyrecorded by the recording mechanism. By locating the time mechanism andre cording mechanism on a support independent of the door carrying thelock such mechanisms are removed from the disturbing conditions incidentto opening and closing or slamming of the door and may be located at anyremote point from the door. This also makes it possible to connect anumber of door-locks and their sev eral recording mechanisms with acentral power-means for operating all of the recording mechanisms of theseries of locks.

The recording mechanism proper comprises a train of gears consisting ofa wheel 9 meshing with a wheel 10 to one side of 'which is a tootheddrum 11 which meshes with a pinion 12 on the shaft of which is anotherpinion 13 in mesh with the teeth of a wheel 14. which has on one face asnail 15 upon the periphery of which bears one end of an arm 16 theother end of which is attached to a sleeve 17 mounted on a shaft 18rotatable within the sleeve, said sleeve also having attached thereto anarm 19 upon the free end of which is fulcrumed by a pivot 20 a two-partstylus comprising the arms 21 and having their rear ends provided withpins 22 fitting in arc-shaped slots 23 formed in a plate 24: fitted tothe angular end of shaft 18 so that as said shaft is partially rotatedin one direction or another the marking ends of the stylus will beseparated or be brought together to make a double or a single line uponthe record-sheet to indicate the different positions of the doorbolt ashereinafter specified, one character of line indicating one position andthe other character a different position of the bolt. The snail-arm 16and stylus fulcrum-arm 19 are spaced from each other by a bushing 25,and a washer 26 and nut 27 may be used to hold the parts assembled Therecordreceiving dial 28 may be of sensitized paper such as commonly usedfor the purpose and graduated radially into hours and fractions thereofas usual, and is held in place by a thumb-nut 29,spring clamp 30, plate31 and adjustable frictionplate 39 as well known in the art. Back of therecord-receiving dial where the stylus makes inscriptions thereon is abacking plate 33, which together with the other parts are attached to abaseplate 34: suitably secured to the casing 1. The train of gearsmentioned is driven from the clock mechanism 2 through a connecting rod35 which has at one end a toothed wheel 36 meshing with a wheel of theclock mechanism and at the other end a toothed wheel 37 meshing with thewheel 9 of the train of gears, the connecting rod being sustained by abracket 08 secured to the base-plate 34. The record-reeeiving dial makesone revolution in Zet hours, and the snail moves the stylus radiallyproportionately to the seven days oi the week as under previousconstructions, and its arm 16 being held in contact with it by a springThe contraction as well as the expansion of the stylus for effecting alighter or a heavier marking for indicating the locked or the unlockedposition of the lock-bolt, for instance a single line for one position,which may be the locked position, and a double line for the other, orunlocked position, or vice versa, is electrically controlled, forinstance by electro-magnets energized and deenergized by a circuitcontrolling switch shifted to its diiierent positions in throwing thedoor or lock-bolt into its locked and its unlocked positions. Adesirable construction for the purpose is as follows.

To the end of the shaft 18 is attached a crank arm 40 which is connectedby a link 41 to one end of a lever 12 tulcrumed at 4:3. This lever isconnected at one side of its fulcrum by a rod is to the armature ot' thepair of electromagnets i, and at the other side of its fulcrum by a rod5 to the armature of the other pair of magnets t so that when one pairof magnets is energized the shaft 18 will be turned in one di rection soas to partially rotate the plate formed with the arc-slots to contractor draw the points of the stylus together to make a single mark orinscription on the dial, and when the other pair of magnets is energizedthe pull on the lever will be to the other side of its fulcrum so as topartially rotate the shaft 18 in the other direction and thus separatethe marking points of the stylus and cause them to make a double or twomarking lines as long as they so remain. One marking will indicate thelock-bolt in one position, and the other marking the other position. Ifthe bolt be thrown. partially quickly in. one direction and then in theother, the stylus will make a short radial mark broader than a singleline marking and not as broad as two lines, and thus indicate amanipulation of the bolt insuilicient however to materially move thebolt to any practical extent.

The switch for controlling the circuits which include the magnets iscarried by the lock-bolt casing and is connected with so as to beactuated from the lock-bolt. A suitable construction for the purpose isa rocking member 46 mounted on a pivot 47 and havin a dog 48 whose pointfits in a recess formed in a part 49 of the bolt 7 "so that as the boltis thrown forward the member 46 will rock in one direction and as thebolt is thrown back it will rock in the other direction. The member 46carries a member 50 which preferably is made of some insulating materialand is attached to the member 46 by a pivot pin 51 so as to oscillateunder the restraint of springs 52, and it carries a contact member 53which has a reduced extremity and back thereof is preferably ellipticalin cross section as shown best in Fig. 4. In the path of to and frotravel of the contact member 53 are two spring contact plates 54 and 55spaced apart from each other and sustained from an insulated support 56,and between these contact plates, near the lower ends thereof, is amember 57 of insulating material supported by a bracket-arm 58 andhaving contact plates 59 and 60 attached to opposite faces thereof.

Contact plates 54 and 59 are in circuit with the battery 5 andelectro-magnets 4 through conducting wires a, b, c, d, and binding posts6, and f, the wire a leading from battery and b to the electro-magnets.Contact plates 55 and 60- are in circuit with battery 5 andelectro-magnets 4 through conducting wires g, h, i, and 7', and bindingposts is and Z, the wire 9 leading from battery and j to theelectro-magnets.

In throwing the bolt 7 from its unlocked position shown in Fig. 2 to itslocked position shown in Fig. 3, in its travel it pulls on the dog 48 soas to rock the member 46 which moves the member 50 and its contactmember 53 upward in the arc of a circle. In its travel the extremity ofthe contact 53 strikes against a retarding member 61 which causes thecontact 53 to lag while the member 46 continues to turn on its axis, themember 50' during such time turning on its pivot and the upper spring 52being put under tension. The

urpose of this lagging is to permit the lockbolt to travel sufiicientlyto engage its keeper before the recording stylus will be actuated torecord the locked position of the bolt. When the member 46 has turnedfar enough for the contact 53 to pass from engagement with the retardingmember the contact member 53, will pass up between and in contact withthe spring contact plate 54 and contact plate 59 on the member 57. Whenthis contact is made the circuit including the pair of magnets 4 isclosed and the magnets energized so as to attract their armature andpull on the lever 42 through the rod 44 so as to close or contract themarking points of the stylus and thus cause the stylus to make a singleinscription line on the record-receiving dial which will. be the lockedposition of the bolt. The contact member 53 will pass from contact withthe spring contact plate 54 and contact plate 59 before or by the timethat the bolt has reached its full locking position, and as soon as itdoes the circuit will be broken and the pair of magnets deenergized,leaving, however, the contact member 53 of the switch standing in araised position, shown in Fig. 3, in which it remains until the bolt isto be thrown into its unlocked position.

In retracting the bolt from its locked position shown in Fig. 2, thebolt carries with it the rocking switch member 46 which causes thecontact arm 53 to move downward in an arc and as its extremity comes incontact with a retarding member 62 it lags until the member 46 hasturned far enough to disengage the member 53 from the retarding; memberwhereupon the recoil of the lever spring 52 will carry the contactmember 53 between and in contact with the spring plate 55 and contactplate 60 011 the member 57, thereby closing the circuit which includesthe pair of clectro-magnets 4 which then become energized and attracttheir armature so as to pull on lever 42 through the connecting rod 45and rotate shaft 18 and its arc slotted plate 24 so as to expand orspread the marking points of the stylus to efl'ect a record on thereceiving dial of two inscribed marking lines which under this form ofthe invention will indicate the unlocked position of the lockbolt, whichinscription will continue to be made so long as the bolt is in itsunlocked position. As soon as the contact member passes from the springplate 55 and contact plate 60 the circuit will be broken and the pair ofmagnets deenergized and the parts will be in the position shown in Fig.2 ready for the next locking operation of the bolt.

In order to prevent cutting or short cirsuiting of the electricalconductors between the recording mechanism and the switch mechanism withthe view of tampering with the operative parts so as to avoid makin arecord of the manipulation of the bolt, the conducting wires a, b, g. j,are associated or inclosed with a bunch or number of other dummy ordisconnected wires as shown at 63 and the whole incased with a covering64 so that a person fraudulently inclined will not know which are theactive and which the inactive wires, and thus additional protectionafforded against fraudulent practices.

To make it impossible to move the bolt in an opposite direction afterstarting to move it in one direction and to compel a completion of itsmovement in the direction started so as to insure the making of a recordof its throw to the looking as well as to the unlocking position andthus insuring a reliable record of the bolts manipulation, a part of thebolt, for instance the plate a9, is provided at one end with a series ofratchet teeth 65 and at the other end with ratchet teeth 66 so inclinedthat the engagement of a locking dog therewith will preventretrogressive movement of the bolt. A dog suitable for the purpose isindicated by the numeral 67, which dog is free to rock or oscillate upona pivot 68 and which will be held in the position to which it is thrownby a spring 69 adapted to bear against one face or the other of the dogaccording to the position into which the dog is thrown. This dog isoscillated so as to change its position and bring one leg or the otherinto operative relation to the ratchet of the bolt, by a pin or stud 7 0carried by the bolt and positioned so that in throwing the bolt in onedirection the pin will strike the underface of one of the legs of thedog and oscillate the latter so that its other leg will be depressed orlowered to engage the adjacent ratchet teeth of the bolt and preventretrogression of the bolt. When the bolt has about completed its throwthe finger or stud will strike the leg of the dog in engagement with theratchet at that end and lift it out of engagement so that the other legwill engage with the ratchet teeth at the other end in which position itwill be held by the spring 69 so that in the throw of the bolt the teethwill glide beneath the leg of the dog but prevented by the dog frombeing moved in the other direction. Figs. 2 and 3 of the drawing give aclear illustration of the operation described. The provision mentionedgives additional security against fraudulent manipulation of the boltand recording mechanism.

The bolt 7 is thrown into locking and into unlocking position by atumbler-lock 71 operable by a key from the outside and having studs 7 2working in a slide rack 73 connected with the bolt, or by a key appliedfrom the inside to the tumbler-lock 7 4- which in its movement willlower the slide rack 7 3 from engagement with the studs of the lock 71,as in an old and well known manner.

In Fig. 12 of the drawing is illustrated the application of theinvention so that a series of recording mechanisms one being employedfor each lock) may be connected to the clock driving means so that therecording mechanism of as many looks as may be employed will all bedriven from the same clock mechanism. To enable that to be done a main.shaft 75 operatively connected with the clock mechanism 2 will havepower transmitting rods 7 6 operatively connected therewith, forinstance by bevel gears 77 and 78 and will extend to the recordingmechanisms 7 9 to be actuated or driven by them. In the drawing onlythree recording mecha nisms are illustrated, and the transmitting rod ofa fourth one. As each of these recording mechanisms will be similar andlike that one already particularly described it is only necessary toshow them in a some what diagrammatic manner, and to the partsillustrated have been applied reference numerals corresponding to thosefor like parts in the figures previously described. It will also beunderstood that each lock will be connected to its appropriate recordingmechanism in the same manner as has been described in connection withthe other figures of the drawing and therefore a further illustrationand description thereof is unnecessary. From this description it isobvious that any number of door-locks in a building may be connected upwith a central power driving means for all the series of recordingmechanisms the advantage of which will be apparent to those skilled inthe art without further amplification.

I have illustrated and described the preferred construction of thevarious parts but it is to be understood that changes may be made in thedetails and the essential features of the invention retained.

The phrase operably connected with the lock-bolt when employed hereinmeans any suitable connection with some suitable part of the lockmechanism by which movement of the bolt will be communicated to therecording mechanism.
